.TO ALL PERSONS TOWHOM THESE PRESENTS SHALL COME:

Be it knownthat I, JOSEPH W. WATTLES, of Canton, in the county of Norfolk, and State of Massachusetts, have made a new and useful invention 0r improvement having reference to Ring Spinning-Frames; and do hereby declare the same to be fully'described in the following specification, and represented in the accompany ing drawings, of which v Figure 1 is a front elevation, and p Figure 2 a vertical and transverse section of a bobbin and spindle, with their sustaining rails and ring-rail and ring, as provided with my invention.

Figure 3 is a horizontal section of the ring-rail and the ring, such section being taken so as to exhibit the slot of the latter, and the pin or screw extending from the rail into such slot.

Figure 4 is a side view of the ring. Y

The nature of my improvement consists principally in the application of the ring to its rail or supporter,

so that while the spinningof the yarn or thread andthe subsequent winding of it on the bobbinmay be in the act of being performed, the ring may be free' to be moved and centralized, and will be so moved and centralized with respect to thespindle and bobbin by the draught of the yarn or thread on the traveller of the ring.

Furthermorewith such an application of the ring to its rail, I provide devices or means by which the ring,

though free to move laterally in diametric directions, will be prevented from vbeing lifted out of place from its I sockpt of the rail by the upward draught of the yarn on the traveller.

In order that the wndingof the thread or yarn on the bobbin may beevenly performed, and the tension of it be rendered uniform, or nearly so, it becomes necessary or very desirable for the ring to be preserved concentric with respect to the bobbin'and its spindle. For this purpose the ring and its rail have .had applied to l them' mechanism for effecting, through manual ageney,.the proper adjustment of the ring vor thecentralizing of it relatively to the spindle. These devices have been, in one case, what are termed adjusting-screws. In

another, the neck ofthe ring, or that part of it which enters the rail, has been turned cylindrical, and eccentric.

with respect to the remainder of the ring, the same being in order that by turning the ring around in its socket, made to fit the neck of the ring, the centre or axis of the ring might be moved into conjunction with that of the spindle. As the guides of the ring-rail become more or less worn', there is a. liability of lateral sway of the spindle and bobbin, whereby their true relations with the ring will be more or less disturbed while the bobbin and the traveller may be in operation.

In the drawings, A denotes the ring-rail, B the ring, C the' traveller, D the' spindle, E the bobbin, and F and G are the spindle-rails.

In carrying out my invention or application of the ring B, I make no use of such adjusting contrivances,

but construct the ring-soeket a. of the rail A with a diameter larger than that of the neck 6 of the ring, so that when the ring is within its socket there shall be an annular space, c c, about the neck of the ring, and-between it and the periphery of the socket, the said socket,however,vhaving a diameter less than the extreme diameter of. the ring. Under this condition of things, the ring, while supported on the rail A., will be free to befmoved in any direction diametrically of the ring and within the socket, and when the traveller is in operation or revolving on the ring, the ring, by the draught o f the thread er yarn, will be kept duly centralized with reference to the bobbin,'for should the bobbin sway laterally any distance, the draught of the yarn or thread on the traveller will almost instantly cause the ring to have a corresponding movement, and thus, surprising as it may appear, the ring when left free to move laterally in its socket will be adjusted concentrioally with the spindle from time to time by the simple operation ordraught of the yarn, as described, thus rendering all additional means,

of adjustment unnecessary. In order to prevent the ring from being lifted in orout of its socket bythe upwardgdraught of the yarn on the traveller, I form the ring with two oblong slots,f, in the neck, and I insert pins or serewsg in the rail A, so as to project into the ring-socket and such slots. The said slots should be longr enough to allow of the proper diametric movements of the ring in the socket.

I claim as my improvement in the ring spinning-frame or machine- A .The application of the ring B to its support-rail Ain such manner that while the spinning of the yarn or thread and the winding of it upon the bobbin may be in 'the act of taking place, the ring may be free to be4 moved and centralized with respect to the bobbin by the draught of the yarn on the traveller.v

I also claim the combination of the screws g, and the slotsfor their equivalent, with the ring and its rail, and withthe ring-socket so formed as to allow the ring to play diametrically, as and for the purpose set forth, the purpose of such screws and slots being as hereinbefore explained.
